To all whom it mdy concern.-

Be it known that we, JAMES B. ORBISON, FREDERICK O. KINGSBURY, and ALVAH J. PRAY, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Seal-Bolts, of which the following is a specification.

Our invention relates to improvements in pins for securing a hasp upon a staple for the purpose of looking a door, and similar looking devices, and consists providing a pin that is split into two equal parts longitudinally, each half being identical with the other, and secured together at one end by a key, which, when the pin is posit-ioned in the staple, secures the pin from being withdrawn without breaking the key. In this manner the opening of the door is impossible without leaving evidence thereof.

This device is especially useful in sealing the side doors of cars, and is adapted to be used in securing any door where it is particularly desired to prevent opening without leaving unmistakable evidence of such wrongful opening and entry. The sealing devices in use are tedious to position and remove, and are not satisfactory in the results obtained by their use.

In the accompanying drawings Figure I is a face view of the pin along the dividing line, the parts being locked together, the lower end being broken away; Fig. II is a plan view of the inner face of one half; Fig.

II is a section along the line AA of Fig. I Fig. IV is an end view, showing sides in position for reception of key Fig. V is a view of the key. Fig. 6 is a view of the bolt in locking position on a staple.

Referring to the drawings in which the same reference numerals indicate identical parts throughout, 1 and 2 represent the parts of the pin, which are identical in construction; 3 is a ridge running longitudinally of each part, near the edge thereof, and 1 is a longitudinal groove or recess; 5 is a transverse ridge and 6 is a transverse recess, near the inner end thereof; 7 is a shoulder near the outer end thereof, formed with a depression 8 therein, for the reception of the key, as hereinafter shown. A ring 9 is cast on the essentially in head of each part, and a circumferential shoulder 10 is cast on the outside of each part near the head thereof.

When the two parts are laid with their fiat faces together, it is seen that a ridge on one face occupies a recess in the other face, and if the parts be held in close contact, one face cannot be moved upon the other either transversely or longitudinally. The cross sectional view shown in Fig. III illustrates the positioning of the parts whereby transverse movement is prevented, and from inspection of Fig. III and Fig. II it will be clear how longitudinal movement is prevented by the engaging transverse ridges and grooves.

The key 19 is inserted through the opening in the lower end left by the parts when in position, as shown in Fig. II said key consists of a head 11 with lugs 12 and 13 depending therefrom, side extensions 14 and 15 are provided to occupy the space left between the lower ends of the parts outside of the shoulders 7 and to give firmness to the union of the parts. In the lower end of each is a cutout or depression 16, into which the head of the key is forced, thereby tending to prevent lateral separation of the parts, the lugs 12 and 13 engage the outside faces of the two parts, and hold the same against lateral separation in a direction at a right angle to that in which separation is prevented by the longitudinal grooves and recesses.

The key is provided with a stem 17, fitted with a spring wire 18, the ends of which diverge; when the key is pressed into engagement with the parts, the spring ends are converged to pass over the shoulders 7, and upon clearing said shoulders, spring outwardly, and contact with the inner faces of said shoulders. It is apparent that the key cannot be withdrawn so long as the. parts remain thus in contact; it is intended therefore, that the head shall be broken off to permit the parts to be separated, and the stem is weakened to render the same frangible.

The ring 9 is adapted to be fitted with a chain whereby the pin may be suspended and attached loosely to the car body and be always ready for use.

The operation of the device is as follows:

The hasp 20, mounted upon the door 21, is positioned upon the staple 22, and with the parts face to face, and the grooves on one face being engaged by the ridges on the other face, the pin is inserted through the staple on the outside of the hasp until the circumferential shoulder 10 engages the staple and limits the further insertion of the pin. The key 19 is then inserted and when it is firmly seated the parts are held against separation thereby at their lower ends, and the staple and chain prevent separation of the upper ends. The key'head is made preferably of the same diameter as the circumferential shoulder, and the play of the pin longitudinally in the staple is limited by said shoulder at one end and said key head at the other end. When it is desired to remove the pin, the head of the key is broken off by a slight tap at one side thereof, whereupon the pin may be withdrawn, and the hasp is free to be swung out of engagement with the staple.

The drawings show a preferable form of embodiment of our invention; other forms of construction involving our idea may be suggested, however, and we therefore desire to claim all such modifications as are within the spirit of our invention.

The pin herein described is separable, and is adapted for use wherever a solid pin could be utilized, but possesses the great advantage over a solid pin that it cannot be removed without leaving evidence thereof, and when it is desired to remove it, the same can be quickly and easily accomplished. It therefore fills the purpose not only of a looking pin, but performs the function of a frangible seal as well. It is much more cheaply manufactured than a padlock, and performs the functions of a locking member with equal success, and betrays its wrongful opening; it is readily opened Without the application of a separate member, as is necessary in the case of the padlock.

In comparison with the ordinary slip bolt or pin, our improved separable pin has the advantage of being readily positioned, as readily removed, and the very decided ad vantage of serving as a lock and a seal at the same time, whereas the slip bolt or pin is merely a stop and is not, strictly speaking, a lock, and is in no sense a seal. It has the advantage over the soft metal seals in use of being much more readily positioned and removed, and serves more effectively to disclose tampering.

It is apparent that our improved pin has many advantages over the pins and seals now in use, and is withal very cheap and simple in its construction.

What we claim as new and desire to secure by Letters Patent is 1. A seal bolt composed of two members adapted to be positioned together with their inner faces in contact, matching grooves and ridges on said faces to prevent asl iding movement of the members on each other, means securing the members at one end, thereof, a longitudinal opening between said members at the opposite end thereof, and a frangible key adapted to be inserted into said opening to lock said members against separation.

2. A seal bolt composed. of two members adapted to be positioned with their inner faces in contact, matching grooves and ridges on said. faces to prevent a sliding movement of the members on each other, means for securing said members at one end thereof, a depression in each of said faces adjacent the opposite ends of said. members, shoulders on said. faces adjacent said opposite ends, and a key adapted to be inserted between said shoulders and engaging therewith. to prevent longitudinal withdrawal thereof, and adapted to lock said members against separation.

3. A seal bolt composed of correspomling members adapted to be positioned. upon each other with their inner faces in contact, means on said faces to prevent a sliding movement of said parts, a longitudinal opening between said parts at one end. thereof, shoulders on said parts projecting into said opening, and. a key adapted to be longitudinally positioned between said parts in said opening, and having means to engage said. shoulders to prevent .\"ithdra\\'al of said key, and having other means to engage said membersexternall y lo lock the same together.

4. A seal bolt composed of identically formed members adapted to be positioned upon each other with their inner faces in contact, means on said. faces to prevent a sliding movement thereof, means securing said members at the upper ends thereof, shoulders on the inner faces of said. members tuljaeent the lower ends thereof, a key constrtnwted to be positioned longitudinally between said lower ends and. having spring means to engage said shoulders to prevent the witlnlrawal of said key, and having means to engage the lower ends of said members externally to lock the same together.

5. A seal bolt composed of correspoinling members, matching projections and depressions on the inner faees thereof adapted to engage when the members are operatively positioned together, internal shoulders adjacent the lower ends of said members, and a frangible key adapted to be inserted longitudinally between the lower ends of said members, said key having a stem provided with spring means to engage said shoulders to prevent withdrawal thereof, and said key having extensions adapted. to engage said members externally to lock the same.

longitudinally In testimony whereof we aflix our signatures in the presence of witnesses.
